LINEN-MARKING MACHINE.

Application filed May 28, 1925. Serial N0. 33,564.

In restaurants, hotels and other public and semi-public places where table and bed linen are furnished to the patron or guest, the practice is to resort to a mark of some kind in order to identify the lawful owner thereof.

The most usual practice is to stamp the name or other characteristic mark on the cloth indelibly so that the washing of the stamped article will not efface it.

In this invention we have shown a small, simple and very effective machine for the marking of all such articles of cloth.

An object of our invention is to produce a machine for the indelible marking of cloth articles, which is inexpensive, which performs its function with the simplest of operations and in an improved manner of increased eiiiciency.

This and other objects are attained in the marking device described in the following specification and illustrated in the accompanying drawings in which:

Fig. 1 is a plan view of the machine em-v bodying our invention.

Fig. 2 is a side elevation of the machine shown in Fig. 1.

Fig. 3 is a plan view of a detailof lour machine.

Fig. 4 is a transverse sectional view taken on the line 4 4 of Fig. 1.

Figs. 5 and 6 are also views of details of our invention.

1n the form of the invention shown, the frame is provided with a detachable article-supporting platen 11 having a rectangular opening somewhat centrally located in the platen and which platen forms a cover for the skeleton upper portion -of the frame 10 also forming a complete table for the reception of linens to be marked as shown in Figs. 1 and 2. Back of this platen ay table 14 is located. This table forms a portion of the frame and carries an inking pad 15. To the rear of the platen side, arms These- 16 and 17 extend from the frame 10. arms carry pivotally the ends 18 and 19 of the handle 2O by means of which the machine is operated. Between the handle and its ends a die holder 21 is pivoted at points 22 and 23 to the handle ends 18 and 19, in position to have the stamp or die 24 which it carries, to rest upon the inking pad when the handle is in the position shown in Figs. 1 and 2. Such a position is always assured by the links 25 and 26 which are connected with the die holder and frame arms 16 and 17 as shown. Vith such a parallelogram connection the dotted line position shown in Fig. 2 may be easily assumed. This brings the die 24 onto the cloth article 27 resting upon the platen 11, so that it may be impressed with the mark.

However, in order that the indelibility of the mark may be assured we have provided for a source of heat located immediately beneath the spot where the die touches the cloth of the article upon the platen through its rectangular opening. This consists of an electric heating unit casing 28 which has its terminals 29 and 30 extending from the side of the frame 10. The electric element 31 of the unit is embedded in refractory cement 32 in the unit casing 33, with a layer of suitable non-combustible yielding l material 34 covering the refractory material 32. This entire unit casing is suspended and detachably secured in position in the frame 10 as shown in the cross section Fig. 4 which has the platen removed. Thus by this heating means the ink is ironed as it were into the cloth under heat and pressure.

The die 24 may be changed in holder 21 by loosening thumb screws 39 and 40, and, in

addition to this, should the heating element ""M or unit burn out it may easily and cheaply be renewed by removing it from the frame 10, instead of having to replace the entire machine.

A further feature lies in the fact that the die is always ready for use in that it rests continuously, When not in use, upon the inking pad and is thereby supplied with ink at all times. This position of rest also serves to keep the ink pad protected from becoming dry and dirty.

Having thus described our invent-ion what we desire to claim is A linen markingmachine comprising a frame, across the frame near its center a detachable rectangular heating unit casing with its top surface Hush with that of the frame, inthe casing embedded in cement therein a heating unit, covering the top of the cement a layer of non-combustible yielding material Hush with the top of the casing,

a detachable article-supporting platen having` a rectangular opening to fit adjacent the casing and mounted on the frame, an inking device located adjacent to the article- Supporting platen, a movable die carrying holder and means for moving the holder from the nking device to the top portion of the heating unit upon the linen to be marked which rests upon the article-supporting platen and back again. 10

ln Witness whereof, We aix oui` signatures.
